Since its launch in November 2007, Android has not only dramatically increased consumer choice but also improved the entire mobile experience for users. Today, more than 150 million Android devices have been activated worldwide—with over 550,000 devices now lit up every day—through a network of about 39 manufacturers and 231 carriers in 123 countries. Given Android’s phenomenal success, we are always looking for new ways to supercharge the Android ecosystem. That is why I am so excited today to announce that we have agreed to acquire Motorola.

. . .

This acquisition will not change our commitment to run Android as an open platform. Motorola will remain a licensee of Android and Android will remain open. We will run Motorola as a separate business. Many hardware partners have contributed to Android’s success and we look forward to continuing to work with all of them to deliver outstanding user experiences.

We recentlyexplainedhow companies including Microsoft and Apple are banding together in anti-competitive patent attacks on Android. The U.S. Department of Justice had to intervene in the results of one recent patent auction to “protect competition and innovation in the open source software community” and it is currently looking into the results of the Nortel auction. Our acquisition of Motorola will increase competition by strengthening Google’s patent portfolio, which will enable us to better protect Android from anti-competitive threats from Microsoft, Apple and other companies.

The combination of Google and Motorola will not only supercharge Android, but will also enhance competition and offer consumers accelerating innovation...
